“Fifth rate” is a Royal Navy term for the largest of the single-deck frigates, square-rigged ships that carry some 44 guns, usually no heavier than 12-pounders. Originally a French design – but quickly adopted by the other European powers – the frigate is used for pursuit, convoy protection, commerce raiding and reconnaissance work. The design’s excellent sailing characteristics and good handling, especially in inshore waters, make it a useful addition to any blockading fleet. The frigate’s ability to operate far away from a home port also makes it a useful cruiser, carrying the fight to the enemy in unexpected waters.

Frigates can have the advantage over larger, two-deck ships in rough waters. A frigate captain rarely has to worry about his gun deck taking on water, and can therefore fight in conditions that leave bigger ships at a disadvantage. However, fifth rates are not powerful enough to face battleships. They have the speed and handling to stay out of trouble; they do not have the strength of construction to survive a pounding! Against sloops, brigs and merchantmen, however, they are deadly. This makes them excellent postings for officers hungry for prize money and glory.
